Countries establish internal economic zones in order to limit foreign investment. make solving disputes easier. have fewer economic restrictions. create manageable amounts of imports.

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's. 

Iwould tell u but its against rules

That’s really nice!

For the sat there is a reading test, math test, and a writing and language test. the act has social studies and science tests.
